Contactor MO 45 (3 Pole, 45A AC-3e)

About this product
Lauritz Knudsen (formerly L&T Switchgear) MO series 3 pole power contactors are AC-4 duty rated contactors for heavy inching, plugging and reversing applications as well as normal AC-3 motor duty, covering 9A to 300A. They conform to IS/IEC 60947-4-1, use a common coil for 50 and 60Hz operation, have low pick-up VA consumption, compact panel-space-saving dimensions, standardised accessories for the 9A-110A and 140A-300A ranges, suitability for both lug and lugless termination, and are RoHS compliant. The 140A-300A frames are available with either a conventional coil or a universal AC/DC electronic coil version. Up to 18A the contactor carries a built-in 1 NO auxiliary contact; 25A to 110A require separately ordered add-on aux blocks; 140A and above are supplied with 2 NO + 2 NC. Standard coil voltages are 110V, 220V, 240V and 415V, 50Hz - the coil voltage suffix must be specified while ordering.

The Lauritz Knudsen CS94570 is a 3-pole power contactor rated 45A in AC-3e and 50A in AC-1. It is used for motor switching and power control.
The Lauritz Knudsen CS94570 suits motor circuits up to 45A in AC-3e duty. It can be combined with a matching overload relay and auxiliary contact blocks to build DOL, star-delta and reversing starters from one product family.
This contactor is commonly used in DOL motor starters, star-delta starters, reversing starters, pump and compressor panels, HVAC control panels, conveyor controls and general power switching in automation panels.
Pair the contactor with a Lauritz Knudsen overload relay whose adjustable range covers your motor's full load current (0.58 × full load current when the relay sits in the winding circuit of a star-delta starter). Common accessories are auxiliary contact blocks, mechanical interlocks for reversing starters, surge suppressors for the coil, and timers for star-delta starters. Check the Lauritz Knudsen catalogue for the accessory part numbers that fit the CS94570.
Select a coil whose voltage and type — AC (50Hz) or DC — match your control circuit supply, for example 24V DC for PLC-driven panels, 110V AC where a control transformer is used, or 230V / 415V AC for mains-derived control. Standard coil voltages for the CS94570 are 110V / 220V / 240V / 415V, 50Hz, and the coil suffix is specified while ordering.
